What is the difference between 4T65E and 4T65E HD?
Physically they are about the same and internally identical but there is really not much at all that interchanges between the two. The big enhancement to the 4T65E was that it uses a pressure control solenoid so the pcm can control line pressure instead of using a vacuum line like the older 4T60E.
How much power can a 4T65E transmission hold?
A stock tranny should hold about 300 WHP, as long as the shifts aren’t too harsh. Otherwise the IS will snap. As long as you keep the shifting reasonable and start raising the power gradually, IMO the chain will go first. It will gradually start to stretch and chatter and eventually snap.
